PIPE-COVER.

Specification of Letters Patent.

Patented Sept. 6, 1921.

Application filed January 15, 1920. Serial No. 351,531.

To all whom it may concern:

Be it known that I, WILLIAM LAFAYETTE GUY, a citizen of the United States, and a resident of Seward, Territory of Alaska, have invented certain new and useful Improvements in Pipe-Covers, of which the following is a specification.

My invention is an improvement 1n pipe covers, and has for its object to provide a cover of the character specified capable of being attached to any pipe wherein a ferrule is permanently secured to the top of the pipe, and a cover is provided having means for detachably engaging the ferrule and having a draft tube extending longitudi nally of the axis of the pipe bowl outside of said bowl.

In the drawings: 7

Figure 1 is a side view of a pipe provided with the improved cover;

Fig. 2 is a longitudinal vertical section;

Fig. 3 is a top plan view of the ferrule.

The present embodiment of th invention is shown in connection with a pipe consisting of the usual bowl 1 and stem portion 2, with which is connected the bit 3. At the opening of the bowl there is arranged a ring or ferrule 4 having a diam ter corresponding to the diameter of the bowl, so that when in place the inner surface of the ring is flush with the inner surface of the bowl.

This ring has a marginal flange 5 which seats upon the top of the bowl and which has openings 6 for receiving screws 7 to connect the ring or ferrule to the bowl. Spiral ribs 8 are provided on the peripheral surface of the ring by embossing the ring or otherwise, and the cover 9 which is dome shaped and fits about the ring closely has grooves 10 shaped to fit the ribs 8 and having the same pitch, the ribs and grooves forming a species of screw thread for looking the dome shaped cover to the ring. From this dome leads laterally a draft tube in the form of an elbow having a relatively short arm 11. and a relatively long arm 12, the short arm ll being connected with the dome while the long arm extends longitudinally of the bowl in parallelism with the axis.

A straight stemmed pipe like. that shown should be smoked in inverted position so that the inlet end of the elbow 1112 is upward, and the fire in the bowl burns from below upward, instead of from above downward. In whatever position the cover is used it prevents the escape of burning bits of tobacco and ashes, making it safe for the pipe to be carried in the pocket even when lighted.

In order to clean or fill the pipe it is only necessary to turn the dome shaped cover a quarter turn, when the ribs and grooves are released and the cover may be removed. The draft tube supplies abundant air for combustion. With the pipe arranged for the fire to burn upward all distillates, like tar and the like, are consumed, or passed out, and do not find entrance into the stem.

The improved cover is intended for use when the pipe is smoked in any place where there is danger of setting fire, such as barns, planing mills and the like, or where exploslves are present or being handled, as well as in the open air when a strong wind is blowing or while the user is driving rapidly. It is practically impossible for fire to escape from the pipe with the improved cover and no smoke or ashes coming from the pipe may get into the users eyes. i

I claim:

1. In combination with a pipe, of a ring secured to the open top of the bowl with its inner face approximately flush with the inner surface of the bowl, and a dome shaped cover having a draft tube, said cover and ring having interengageable means for holding the cover in place, and a draft tube leading outwardly from the dome and thence longitudinally of the axis of the bowl to near the bottom of the bowl.

2. In combination with a pipe, of a ring secured to the open top of the bowl with its inner face approximately flush with the inner surface of the bowl, and a cover having a draft tube, said cover and ring having interengageable means for holding the cover in place, and a draft tube leading outwardly from the dome and thence longitudinally of the axis of the bowl to near the bottom of the bowl.

3. In combination with a pipe, of a cover having a draft tube, said cover and pipe having interengageable means for holding the cover in place, and the draft tube leading outwardly from the dome and thence longitudinally of the axis of the bowl to near the bottom of the bowl.

4. In combination with a pipe, of a cover for the bowl having a draft tube extending longitudinally of the bowl.

WILLIAM LAFAYETTE GUY.
